Le Varta sarebbero le migliori??
Solo a chiacchiere di marketing. Ci sono batterie meno blasonate ma di gran lunga migliori per durata ed efficienza.

Concordo pienamente con la classifica 👏. Ho sempre scelto FIAMM per le mie auto e la differenza si sente: la Ecoforce AGM mi ha dato partenze sicure anche a -10°C e dopo 4 anni mantiene ancora uno spunto perfetto. È bello vedere un marchio italiano ai vertici mondiali per qualità e durata. Ottimo lavoro Gianni, spiegazione chiara e dati tecnici che confermano quello che chi usa FIAMM da anni già sapeva: è una garanzia.
